nl'rnovmmm' ne shoarma-Mamma 'mBohodubmedtomtheoeLettenPuntmdrnnking'putoftham To 'all whom it 7ma/y concern Be it known that we, Mano Bslcrmsmcn and SAMUEL Gomr, of Paris, France, have invented an ImprovedBlowing-Apparatns; and we do hereby declare `the following to be a full, clear, and exact description of the same.

Our improvement consists, first, of an annular chamber in the casing of a blowingapparatusfor the accumulation of the air driven from the centre of the ap# paratus.

Our improvement further consistsin the substitution, for the wings ordinarily employed, of a circular brush, of bristles, whalebone, or wire, by the use of which the disagreeable noise occasioned by ordinary blowers is prevented.l

` AIn order to enable others skilled in the artl to make and use our invention, we will now prpceed-to describe its construction and operation, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1, SheetNo. 1, is a vertical improved blowing-apparatus; Y 1 2, asectional elevation on the line 1-2, iig. an

Figures 3 and 4, Sheet No. 2, are modifications of our invention.

The casing A of the apparatus consists of two sections, a and a', which are connected by screw-bolts, the sections being so formed that, when together, they enclose the circular fan-chamber-f, and the annular airchamber f, which communicateswith the sn-chanber through a narrow passage, z.

Air is admitted to the fan-chamber through opensection of our ings d, on each side of the casing, and with the4 air'` y receptacle f communicate radial tubes f', for .the 'exit of the air; these tubes either communicating with sep-l arate ppes'or with a single curved pipe, so astodirect the whole current of air toV one point.

To central'spindle, i, turning in bearings -in brackets ,proccting fromithe sections a a", is secured -the nave a circular lbrun b,the latter consisting of bristles, wire, or other 'A table material. .I

Letters Patent- V '1. A blowingfapparatus, consisting of a casing, with @are must be taken to suiiiciently separate,attheir bases, the bunches of bristles or other v.material which forms the brush, that the air may pass tothe centre of the apparatus, from which it is driven by the rotation of the brush through the passage z, and into the cham-` ber'f. v Owing Ato the iiexiblityof the iibes ci' the brush, they'will be maintained in contact, or nearly in contact, with the walls of the chamber, so that the roaring noise produced by the counter-currents of air which 'are formed between the walls of the chamber and the vanes of a fan, when the latter is used, is prevented.

Inasmuch as the opposite sides of the chamber fl are concave, instead of ilat, as in ordinary blowers, the passage of air'om the same is greatly facilitated, and the formation of eddies is prevented.

i In fig. 4,'the brush is represented as applied to an l We claim as our invention, and desire to secure by openings arranged .for the passage of air, and within which revolves a fan, consisting of ilex'ible filaments, substantially as described.

2. The casing, with its 'chambers f f,e x, inlet and exit-passages, and revolving fau or brush b',

4 the whole being constructed and arranged substantially as and for the purpose specied.

In testimony whereof, we have signedour names to this specicatiomiu the presence of two subscribing witnesses.
